642-644 33rd Ave, San Francisco, CA 94121

The two-unit residential building at 642-644 33rd Avenue in San Francisco's Outer Richmond district is a two-story flats and duplex structure built in 1925, currently owned by Lee Jackson L & Judy L. The property's permit history shows several significant modifications over the years, including the 1991 legalization of a living floor in the ground floor and earlier (1985) improvements that added a half bath and playroom in the basement.

More recently, in 2016, there was an attempted ground floor remodel project that included adding two bathrooms, a bedroom, storage room, and game room, though this electrical permit was ultimately canceled. The building has experienced some maintenance and compliance issues over time, most notably a housing inspection complaint filed in September 2019 regarding peeling paint on the exterior, which remains listed as "Not Active." Additionally, there was a complaint in 2004 about an illegal unit without proper permits, though this too is no longer active.

The property has a recorded noise complaint from February 2021 concerning excessive noise, which was accepted but not escalated. Recent service requests include a blocked driveway complaint in September 2024, though this was closed as invalid due to incomplete reporting information. The area around the building has experienced minor issues with abandoned vehicles, with reports in 2019 and 2017 showing vehicles that were gone upon the arrival of enforcement officers.
